Cusco Peru is the ancient capital of the Inca empire and the gateway to Machu Picchu, a beautiful colonial city built on Inca stone at 3,400 metres in the Andes. Almost every Peru trip runs through it: it is both a destination in its own right, with cobbled streets, grand plazas and world-class museums, and the base for the region’s greatest day trips. Give it a few days, respect the altitude, and Cusco becomes the heart of your Peru.

Cusco Peru: The Ancient Inca Capital
Cusco Peru was the political and spiritual centre of the Inca empire, and it still wears that history openly. Massive Inca walls of precisely cut stone form the foundations of Spanish colonial churches and mansions, most famously along the Hatunrumiyoc street and at the Qorikancha sun temple. The Plaza de Armas, ringed by arcades and two grand cathedrals, is the living heart of the city.
Above the centre, the bohemian San Blas neighbourhood climbs the hillside in a maze of white-walled lanes, artisan workshops and cafes with valley views. Cusco is compact enough to explore on foot, though the altitude means you will do it slowly at first, which is no bad thing in a city this rich in detail.
Things to Do in Cusco
The best things to do in Cusco begin in the historic centre: the Qorikancha, the Cathedral on the Plaza de Armas, and the San Pedro market for a taste of local life. On the hills above town, the Inca site of Sacsayhuaman, with its colossal zig-zag walls, is an easy half-day and a superb sunset spot. Museums of pre-Columbian art and Inca history fill in the story.
Beyond the sights, Cusco rewards wandering: San Blas at dusk, a chocolate or cooking workshop, and the cafes and restaurants that have made it one of South America’s best food cities. Two full days cover the city itself before you turn to the day trips around it.
Cusco Day Trips: Using the City as a Base
Cusco’s real magic is as a base, and the best Cusco day trips are world-class. The region around it holds the greatest concentration of sights in Peru, and almost all of them are done as day trips or short overnights from the city. Machu Picchu is the headline, reached by train through the Sacred Valley. Closer at hand, the Sacred Valley towns of Pisac and Ollantaytambo, the striped Rainbow Mountain, the turquoise Humantay Lake, and the Maras salt pans and Moray terraces all make classic outings.
The practical implication is simple: build your Peru itinerary around Cusco, give yourself enough nights to fit the day trips without rushing, and remember that everything here happens at altitude, so pace the big hikes for later in your stay once you have adjusted.

Coping with the Altitude in Cusco
At 3,400 metres, Cusco sits high enough that most visitors feel the thin air on arrival: mild breathlessness, a light headache, or trouble sleeping the first night. It is usually harmless and passes within a day or two, but it is the single thing to plan for. Take your first day very easy, drink plenty of water, go gently on alcohol, and lean on coca tea, which is offered everywhere.
Crucially, spend your first couple of days in Cusco itself or lower in the Sacred Valley before attempting the high hikes to Rainbow Mountain or Humantay, both well above 4,000 metres. Acclimatising properly in the city is what makes the rest of the region enjoyable rather than a struggle.
Best Time to Visit Cusco
The best time to visit Cusco is the dry season, from May to October, when days are sunny and clear and the trails to Machu Picchu and the mountains are at their best. June to August are the peak and busiest months, and they include the great Inti Raymi festival on 24 June, the reenacted Inca Festival of the Sun. The shoulder weeks of May and September or October balance good weather with thinner crowds.
The wet season, November to March, brings green landscapes, fewer tourists and lower prices, but also afternoon rain and the annual February closure of the classic Inca Trail. Whatever the season, Cusco nights are cold year-round because of the altitude, so pack warm layers.
Is Cusco Peru Safe?
Is Cusco Peru safe is a common question, and for visitors the answer is generally yes, with normal city precautions. The tourist centre, the Plaza de Armas, San Blas and the main streets are well travelled and well policed. As anywhere, keep an eye on belongings in crowded markets and on buses, use registered taxis or rideshare apps at night, and avoid quiet areas late.
Occasional strikes or protests can disrupt transport in the wider region, so it is worth checking the current situation before big travel days. For the everyday visit, though, Cusco is one of the more comfortable cities in Peru, well used to international travelers and geared around them.
Cusco to Machu Picchu and Getting Around
The Cusco to Machu Picchu journey is the trip most visitors build around. There is no road all the way; you take a train from Cusco or the Sacred Valley to Aguas Calientes, then a short bus up to the ruins, or you walk in on a multi-day trek. Trains book out in high season, so reserve well ahead. Within Cusco itself, the centre is walkable, and taxis and rideshare apps handle anything further at low cost.
Common Questions, Answered
How many days do you need in Cusco Peru?
Plan three to four days at least: two for the city itself and one or two more for day trips such as the Sacred Valley or Rainbow Mountain, plus the time for Machu Picchu. Building in acclimatisation days makes everything easier.
How high is Cusco and will I feel the altitude?
Cusco sits at 3,400 metres, and most visitors notice the thin air on the first day. Take it easy, hydrate, use coca tea, and acclimatise here before the higher hikes to Rainbow Mountain or Humantay.
What are the best things to do in Cusco?
Explore the Plaza de Armas, the Qorikancha and San Pedro market, wander San Blas, and visit Sacsayhuaman above the city. Then use Cusco as a base for the Sacred Valley, Rainbow Mountain, Humantay Lake and Machu Picchu.
How do you get from Cusco to Machu Picchu?
Take a train from Cusco or the Sacred Valley to Aguas Calientes, then a short bus up to the ruins; alternatively, walk in on a multi-day trek. Trains sell out in high season, so book ahead.
What is the best time to visit Cusco?
The dry season from May to October offers the clearest weather and best trail conditions. June includes the Inti Raymi festival. The wet season is greener and quieter but brings afternoon rain and the February Inca Trail closure.
Is Cusco Peru safe for tourists?
Generally yes, with normal city precautions. The tourist centre is well policed; keep valuables secure, use registered taxis or apps at night, and check for regional strikes before big travel days.
In short, the best things to do in Cusco split between the historic city and its day trips; the best time to visit Cusco is the dry season, May to October; and anyone asking is Cusco Peru safe can travel with normal city caution, minding the altitude above all.
Cusco is the heart of a wider Peru trip, and many travelers add the Galápagos to a longer South America route.

The Bottom Line
Cusco Peru is the indispensable heart of any Peru trip: an ancient Inca capital that doubles as the base for Machu Picchu, the Sacred Valley and the great mountain day trips. Give it three or four days, take the altitude seriously on arrival, come in the dry season if you can, and let the city set the rhythm for the whole region.
